如何在 Java 中向 Guava 多图的所有键添加单个值

Question

How to add one single value to all keys of a Guava multimap in Java?

For example, I create a multimap with an ID and a String:

    final Multimap<Integer, String> myMap = HashMultimap.create();
      myMap.put(0, "snake");
      myMap.put(1, "crocodile");
      myMap.put(2, "turtle");

Now I want to add one entry "reptile" to all keys. After that, my map should look like this:

    {
        0=[snake, reptile], 
        1=[crocodile, reptile], 
        2=[turtle, reptile]
    }

Answer 1

myMap.asMap().values().forEach(v -> v.add("reptile"));
